I keep getting calls from this number at all hours of the day. It belongs to Blue Cross/Blue Shield Of Michigan. I have contacted them several times but this hasn't stopped the calls entirely. They tell me that somehow when they're dialing a conference call number that it connects to my cell phone.
This is especially annoying when I'm in Europe on business and it wakes me up in the middle of the night.
You are correct. This number shows up anytime we dial out from our meeting rooms or desk phones. It is not a direct number to a particular person. It could be a problem in the lines??
